Data Handling (Sowing and Modelling Data)
NCERT Mathematics for Class 7, Chapter 3, Data Handling, starts with children sowing seeds and recording what sprouts. It collects and organises observations into tables, finds the average as mean and the middle and most common values as median and mode, and draws bar graphs that make comparisons visible. Tossing coins and rolling dice introduce chance and simple probability. Children choose which average fits the story, read graphs critically, and plan small surveys from question to conclusion.
